Distance measuring apparatus

A camera, comprising:

• a photometering device that measures a brightness of an object in a plurality of photometering zones;
• a light receiving device including a plurality of distance measuring zones defined by at least a part of said plurality of photometering zones, and at least one array of photoelectric conversion elements, wherein each photoelectric conversion element converts light received thereon into an electric charge that is accumulated, the accumulated electric charge being output in order from each photoelectric conversion element as an analog picture signal of the light receiving device;
• an A/D converter which performs A/D conversion of the analog picture signal to obtain digital image data;
• a transformation range setting device which sets a transformation range corresponding to photometering data of the photometering zones that overlap the distance measuring zones;
• a logarithmic transformation device which performs logarithmic transformation on the digital image data at said set transformation range to obtain sensor data;
• and
• a calculation device which calculates an object distance based on said sensor data.
